McDonald's will bring you food if you will please just open the door

You want food, you want it to be cheap, and to consist largely of substances scientists would tell you are absolutely terrible for you... if only the lab could figure out what they are. But who has the time?

Or the energy to get up off the couch? (Or out of bed, if you have not yet made it to the couch; it is only 2:00 p.m.)

And then you wind up walking out to your car or bicycle. And at that point, you've still got several minutes of treacherous urban traffic before you must 1.) speak to another human, 2.) dig into your pocket, 3.) no, the other pocket, 4.) pay the youth behind the counter, who hates you, 5.) wait for the culinary team to assemble your food-stuff and make it hot, salty, sweet, and gooey enough that your brain does not hesitate to think about what you're ingesting or all the mistakes you've made.
